Problem 46 Chapter 7 -HW 5 orque orque orque

Problem 23 Chapter 7 -HW 5 orque orque orque 23. (II) A block of mass m is attached to the end of a spring (spring stiffness constant k), Fig. 8– 35. The mass is given an initial displacement x 0 from equilibrium, and an initial speed v 0 Ignoring friction and the mass of the spring, use energy methods to find (a) its maximum speed, and (b) its maximum stretch from equilibrium, In terms of the given quantities.

Problem 33 Chapter 8 -HW 5 orque orque orque 33. (II) A 96 -kg crate, starting from rest, is pulled across a floor with a constant horizontal force of 350 N. For the first 15 m the floor is frictionless, and for the next 15 m the coefficient of friction is 0. 25. What is the final speed of the crate?

11 -5 Angular Momentum and Torque for a Rigid Object orque orque orque Example 11 -8: Atwood’s machine. An Atwood machine consists of two masses, m. A and m. B, which are connected by an inelastic cord of negligible mass that passes over a pulley. If the pulley has radius R 0 and moment of inertia I about its axle, determine the acceleration of the masses m. A and m. B, and compare to the situation where the moment of inertia of the pulley is ignored.
